Part Number: ADS1226
Hello,
It is not very clear for us when the self-calibration is needed.
We are using now the ADS1226 in high-resolution mode with the 2 channels active and performing a self-calibration each time we read a channel.
This gives use a maximum period at about 1/800ms (793ms) for reading 2 channels.
Today we need to have a higher sample rate and still need the precision. So I have 2 questions:
- Is the calibration performed valid for both channels?
- With a temperature that may vary within almost the whole operating range, how often do we need to perform the calibration?
Thanks a lot.
